EYE AND HOOK FORMER.

Specification of Letters Patent.

Patented Feb. 10, 1914.

Application filed February 26, 1913. Serial No. 750,937.

To all whom it may concern Be it known that I, ARTHUR J. NEWTON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and usetul Improvements in Eye and Hook Formers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to appliances for forming hooks or eyes out of metal rods and more particularly to the class of devices used "for producing welded eyes.

One object of my invention is to provide a bending appliance adapted to perform both the initial and the final bending operation upon the rod without having the rod withdrawn from the members between the said operations.

Further objects are to provide a. bending appliance adapted interchangeably for forming either open hooks, closed but un- Welded eyes, or welded eyes; also for tapering the end of the hook during the bending operation.

To this end, my invention consists of the novel arrangement of parts herein disclosed, one embodiment of which is shown in the accompanying drawings, in which- Figure 1 is a side view of one of the laterally separable parts and of the member longitudinally movable with respect thereto. Fig. 2 is a vertical section through the laterally separable parts of the device. Fig. 3 is an end view of the left-hand portion of Fig. 1. Fig. 4 is a sectional view of the parts shown in Fig. 5 along the line 4-4. Fig. 5 is a view similar to Fig. 1, showing the bending forming and squeezing a welded eye. Fig. (3 is a vertical section through Fig. 5 along the line 6-6. a

In the embodiment shown in the drawings, the device of my invention consists of a pair of members movable relatively in a direction longitudinal of the rod from which the hook or eye-bolt is to be formed, one of these members comprising two laterally separable portions 1 and :2, each of the said parts having upon its inner face a longitudinal recess 3 slightly wider than half the diameter of the rod upon which the hook or eye is to be formed. The member 2 has a semi-cylindrical indentation 4 as a continuation of the redevice of myinvention as used incess 3, this indentation 4 being opposed to a PI'OJBCtlOIl 5 on the member 1, whereby the space between the said projection and indentation becomes substantially a curved continuation of the longitudinal recess or slot 3 when the laterally separable parts 1 and 2 are brought together. Consequently, if a bar of steel is inserted between the parts 1 and 2, as shown in dotted lines by 6' in Fig. 4 and the said parts are then forcibly brought together, a book 7 will be formed upon the bar 6.

Adjacent to the coacting formations 3 and 4, each of the laterally separable members has upon its face a longitudinal slot, semicircular in section and adapted to receive the hook-shaped end of the rod as shown in Fig. 4, when the end of the hook is turned vertically upward, there being boss tormations 7 and 8 upon the opposed faces of the said members adapted to enter the interior of the said hook. Upwardly of the said bosses, I provide upon the opposed faces of be members 1 and 2 the lateral halves of the chambers 9 having curved upper walls leading to a rearwardly enlarged opening 18. llearwardly of the said chambers when the same are laterally adjoined, I position a pawl 11, pivotally mounted upon a member 12 longitudinally movable with respect to the members 1 and 2, the said pawl. 11 having a tip portion 13 adapted to enter the chambers 9 and to be laterally guided by the lateral walls of the said adjoined chambers. When the member 12 carrying the pawl 11 is approached longitudinally to the adjoined members 1 and 2 with an upturned hook end held between the latter, as in Fig. 1, the tip' 13 of the pawl will impinge against the upturned end 14 of the hook and will cause the said end to coil around the bosses '7 and 8 interiorly of the same until the end 14: impinges against a solid portion of the die member 1, such as the shoulder 15. Then it the approaching of the pawl to the members 1 and 2 is still continued, theupper edge of the pawl will impinge against the curved upper walls 19 of the said members which will serve as cam surfaces, coacting with the said pawl to force the tip of the latter downwardly, thereby compressing the tip of the hook. By varying the extent to which the pawl is moved into the recess and along the said cam surfaces, and by varying the shape of the grooved tip 13 of the pawl, this compressing of the tip of the hook maybe varied able means, such as a counterweight l6 positioned on the pawl at the opposite side of the pivot 17 from the pawl tip 13.

If the appliance of my invention is to be used for forming eyes instead of hooks, the laterally disposed hook forming dies of Fig. 1 are replaced by similar members having bosses permitting a complete coiling of the upturned end 14 of the rod, as shown in Fig. 5. By heating the end of the rod sufliciently before erforming the operations just described, and by approaching the pawl member far enough to cause its tip to be forced downwardly for a considerable distance (as in Fig. 5) the eye may be coiled and welded at one operation.

It will be evident that by varying the extent to which the pawl is' approached thereto, the same set of dies can also be used for forming tightly or closely closed, but unwelded eyes. The methodsof moving parts of such appliances relative to one another, as by mounting the same on upsetters, are so well known to those interested in the making of eyes or hooks, that they do not require description here. By altering the shapes of the coacting parts, hooks or eyes may be formed from square or flat stock instead of the round stock shown in the drawings. Moreover, many of the details herein dis closed might be varied considerably without departing from the spirit of my invention, hence I do not wish to be limited to the exact arrangement of parts which I have shown and described.

I claim as my invention:

1. A bending appliance comprising apair of laterally disposed members adapted to re ceive a hook-ended metal rod therebetween, there being cam surfaces carried by the said members; a member movable longitudinally with respect to the aforesaid laterally disposed members; and a pawl carried by the said longitudinally movable member and 7 adapted to engage the said cam surface, the

said pawl coacting with the said cam surface to cause the pawl to close the hook on the aforesaid metal rod upon the longitudinal approaching of the said members.

2. A bending appliance comprising a pair of laterally disposed members adapted to receive a hook-ended metal rod therebetween,

1 there being cam surfaces carried by the said members; a member movable longitudinally with respectto the aforesaid laterally disposed members; and a pawl pivotally careas es ried by the said longitudinally movable member and adapted to engage the said cam surface, the said pawl coacting with the said cam surface to cause the pawl to close the hook on the aforesaid metal rod upon the longitudinal approaching of the said members.

3. A bending appliance comprising a pair of laterally disposed members adapted to receive a hook-ended metal rod therebetween, there being cam surfaces carried by the said members; a member movable longitudinally with respect to the aforesaid laterally disposed members; and a counterweighted, pivoted pawl carried by the said longitudinally movable member and adapted to engage the said cam surface, the said pawl coacting with the said cam surface to cause the pawl to close the hook'on the aforesaid metal rod upon the longitudinal approaching of the said members.

4:. A bending appliance comprising a pair of laterally disposed members adapted to receive a hook-ended metal rod therebetween, there being cam surfaces carried by the said members; a member movable longitudinally with respect to the aforesaid laterally disposed members; and a pivoted, gravity returned pawl carried by the said longitudinally movable member and adapted to engage the said cam surface, the said pawl 00- acting with the said cam surface to cause the pawl to close the hook on the aforesaid metal rod upon the longitudinal approaching of the said members.

5. A bending appliance comprising apair of laterally disposed, relatively movable members adapted to receive a metal rod therebetween, there being upon the opposed surfaces of the said members coacting formations adapted to form a hook upon the metal rod upon approaching of the said members; there being also upon the said opposed surfaces guide formations for receiving the portion of the metal rod thus formed into a hook, and cam formations adjacent to the said guide formations; and a pawl carried by a pivot movable longitudinally relative to the said laterally disposed members, the said pawl coacting with the said cam formations to cause the pawl to close the hook on the aforesaid metal rod upon the longitudinally approaching of the said pivot to the said laterally disposed members.

In testimony whereof I have signed my name in presence of two subscribing wit- 1 nesses.
